Spreadsheets break.
Errors compound.
Audits loom.

Bitcoin moves fast. Transactions pile up. Lightning settles instantly. Wallets multiply. Your spreadsheet can't keep up.

You need precision. You need scale. You need books that close.

Specialization

Bitcoin-native

Built for multisig and the complex transactions legacy tools choke on.

  • Reconcile multisig wallets automatically. No manual matching.
  • Account for channel opens, closes, and force-closes, not just payments.
  • Handle on-chain fees and change outputs without inflating gains.
  • Account for L-BTC and Liquid assets like USDt alongside your BTC
